This was Steve McQueen's breakout role and I can see why. He does not have that much screen time, but he makes the most of every scene he is in. The jungle parts are okay, but they could have lost the whole Frankie and Gina romance thing and no would miss it. There was just no chemistry there. Actually the Burmese girl was more his type, except for the whole spy thing. Then there is Peter Lawford. Kind of disappointing. He seemed to be just collecting a paycheck. The rest is okay. It was worth 2 hours to see McQueen's first staring role, but I would not pay to see it again.
